This invention relates to certain novel improvementsl in meat cutters and has for its principal object the provision of an improved construction of this character Which Will bel 5 highly efficient in use and economical in manufacture., n Y

In meat cutters or grinders with which I am familiar prior to my invention, the conventional construction includes a rotatable I6 feedervvhich feeds the meat to a perforated plate for passage therethrough subsequent'to the cutting of the meat. This cutting ofthe meat is brought labout by a rotatable cutter including blade members movable over; the inner face of the plate. blades thereof are rotatable with the feeder and designed to rotate in circular fashion. In the mounting of the blades they are arranged'at right angles With. respect to each other for this circular movement. In making the circularmovement it is manifest that the meat is forced through-the openings of the plate rather than first being cut or ground. This'res'ults because of the fact that the blades do not move so as to create a shearing cutting action on the meat and consequently the meat l is packed against the plate to be forced through the openings thereof. By reason'of this jamming themeat gets packed tight in the perforations, especially *near thel center part of the plate.. causes the meat to become hardened and consequently a friction the meat. The meat ed by' friction results albumin therefrom and n consequently the meat emerges atsome time during the cutting operation in a spoiled state or condition.vv

have'found that if these blades take a movepacking and being heat- .i4-i mentY over the face of the plate Which Wouldl result in a shearing action that the' meat will be effectively cut prior-to passage through the perforations in the lplate and the collection ofspoiled meat will be eliminated-toI a m maximum degree. It is, therefore, one of the vThis cutter vand the lThis packing of the meat Vis created which heats in the burning of all theV manyv objects these 'diliiculties which-will move over shearing cuttingiaction upon to its passage through theV openings in the.`

plate.

, I have also foun'dfthat mitted 'to' collect adjacent. thel hubT of the blade, vby reason that such throughvthe openings, comes hardened and of this invention to eliminate and to overcome these disad-l vantages and to vprovide a cutter g structure the plate to effectuate v the meat prior -fvvhere meat isl perthe collected meat becreate a friction rand ultimately ruins or de# teriorates the cutting y value this point. It is,

objects of this difficulty.

Other objects therefore, one of the manyv meat is not forced consequently tends tol of the blades' atv .i

invention Ito overcome" this t VWillappearhereinafter. .f

The invention consists inthe novel combinationand arrangement of parts to be vhereinafter-described vand claimed. v Y

The invention `vvillv be best understood by reference to the accompanying showing the preferred formv of construction and in which:

Fig. 5 is -afragmentary sectional detail I view of the cutter structure line 5-5 ofFigQ;- A n to the drawing, he conventional ti allyfon the Referring taken substanmeat grinder usually vcomprises a casing 10' through which the :meat to be ground is fed.

The meat is'introduced `to this. casing l() through a funnel shaped mouth l1. .'Mounted in the ,casing l0 is a feeder l2'supported by a shaft 13 having one end portion journaled in a suitable bearing 14 and carrying a handle 15 whereby manipulation of the feeder is brought about. The opposite end portion ofthe feeder is j ournaled in a plate 16, which plate is mounted againstV a shoulder 17 provided by the discharge end 18of the casing 10. Y This plate 16 is provided Vwith a plurality of perforations 19 through which the meat after being cutis adapted to pass. The plate 16 may be mounted `in any approved manner upon the casing as will best serve the purpose. j

Mounted for rotation with the feeder 12 is a holder 2O including a hub portion 21 having a substantially square openingv 22 formed therein for mounting upon a square shaped` 13. This holderv 1s portion of the shaft mounted on the shaft 13 at the innersideof the plate 16. Extending from this hub portion arearms 23. These arms are-arranged in alternate order upon the hub 21. Y. 'That is, the arms on opposite corresponding sides of the hub are arrangedV offset lwith respect to each other so as Yto dispose these arms o'n oppositesides of'a-transverse-line through the I Ycenter of the hubV whereby to dispose their atAk side portions '24 lflush with the side walls 25, of the hub. Each arm is provided at the edge with alongitudiadjacent the side portion 24 s nal` groove 26 which constitutes a continuation of a groove 27 formed grooves there are adapted to be mounted the cludeshank portions 29 adapted forinsertion in the grooves. l The outer end portion 30 of theblade is tapered'upwardly and outwardly from the shank portion 29- so asv to dispose this portion upon a beveled surface .31 provided by the'arms on the outer sides ofthe grooves.

To complete the mounting of the lblades Vthere may be provided a substantially square shaped-'ring k32secured to the face of the hub byscrews33 so that the ring will be clamped againstadjacent por-k tions of the blades Vwhereby to effectuate re- Y movable connection ofthe blades with the at theY edges nearest the direction of rotationY holder.

It will be seen that .the inner end portion ofeach blade extends to a position which overlaps the arm adjacent tothe arm carrying' the blade. prevent the collection of meat or other ingredients or bony matter from collecting beneath the arms adjacent the hub portionV ofthe holder. j i v It will'be seen that by disposing the blades of the blades vinstead ofA at the. outer edges or the edges kfarthest away from the direction lof rotation of the blades that the blades are disposed parallel with the transverse center `Vline of the hub and at-one side thereof and consequently `when the hub is rotated the blades will move over the plate in shearing` f, ting the meat in the edge adjacent the side wall 25 of the hub. In these The'reason for this isfto vance of eachelement.

I ment with respect contact with the-meat thereby eectiv'ely cutpriorto its passage through 'the openings. meat it will be seen that the possibilities of the meat clogging in the'fopenings of the plate 16 will be reduced to a minimum. Also, the blades with their inner ends extending beyond the transverse center line will move over the holes adjacent the center of the'hub and consequently cut such meat as might find movement to this point and will, therefore, `force the meat through. the openings nearest the center of the plate and thus prevent'collection of the meat within this area, which vcollection of the meat will result in the hardening of the meat and subsequent spoiling by heat created by friction.

' I have found by the use of a cutting structure as described herein that the meat is more efliciently ground or cut prior to its passage through the perforations in the plate and consequently the holes in the plate do not become plugged and the blades dull by reason of collection and hardening of. meatat such points where they meat otherwise'if not properly cut would netpass through such openingsV or perforations.

vWhile I, have illustrated and f described the, preferred form of construction. forV carrying my invention into effect, this isoapable of, variation and modi-lication, without r the spirit ofthe invention. j

departing from I, therefore, do

not wish tofbe ilimited to the precise details of construction set forth, Y Y 100 but desire to .avail myselfof such variations and modiiications'as come within of the appended claims.

lHaving thus described my invention whatv I'claim as new and desire 'to protect by Letters Patent.y is:`
